Google Cloud End Point Error: Process exited before success message

Question

我在运行 appengineStart 任务时遇到这个错误。

print of the error

错误显示：“com.google.cloud.tools.appengine.cloudsdk.internal.process.ProcessRunnerException：进程在成功消息之前退出”

我在 Google 上搜索过，但找不到解决方案。

这是完整的错误日志：

Configuration on demand is an incubating feature.
Gradle now uses separate output directories for each JVM language, but this 
build assumes a single directory for all classes from a source set. This 
behaviour has been deprecated and is scheduled to be removed in Gradle 5.0

Answer 1

Could not open the requested socket: Address already in use: bind 表示您之前启动了一个开发服务器但它没有正确退出，或者您有另一个进程使用相同的端口。您需要终止违规进程（或重新启动计算机，效果相同）或 change the port on which your dev server runs。本质上，将以下内容添加到您的 gradle 文件，并根据需要更改端口：

appengine.run.port = 8888
